No, we are not in a chemistry lab.
It reminds you of Le Labo? You are not far. It is a newly opened perfume concept store in Paris, with a reasonable name NOSE.
With several niche perfume or fragrance brands, you can just find your proper scent which is different from the mass market so-called luxury brands. They provide you Francis Kurkdjian, Odin, Lorenzo Villoresi, Penhaligon's etc.
The most fascinating thing in this boutique is their perfume diagnose system. It is a made-to-order diagnostic system in order to give each customer their own scent. You registered your preference among the perfumes and the system will give you the result of your favorite oder from head notes, middle to base notes.
Afterwards, they will provide you several perfumes to try on, you smell, you note, you give another round of preference selection; finally you will get the real scent you are looking for.
Interesting test I've ever done.
My next bottle of perfume will be from Francis Kurkdjian...
Have a nice Saturday.
